ecw2tiles's Introduction

Schritt für Schritt

  • Optional: Dateien runterladen

  • ECW/EWW-Dateien in einem VRT-Index sammeln: gdalbuildvrt -addalpha -hidenodata mosaic.vrt ecw/*.ecw

  • Optional kann man die mosaic.vrt schon in QGIS anschauen

  • Mosaic in Tiles zerlegen:
    gdal2tiles.py -p mercator --resume -z '0-18' -s 'EPSG:25833' -w none mosaic.vrt tiles

    Unglücklicher Weise generiert gdal2tiles.py PNG-Kacheln in der falschen Nummerierung (y-Achse gespiegelt). Also die Kacheln sind nicht von oben nach unten, sondern von unten nach oben durchnummeriert. Daher habe ich ein kleines convert.js-Script in node.js gebaut, das mit GraphicsMagick die Farben verbessert, Transparenz durch eine Hintergrundfarbe ersetzt, und die vertikale Nummerierung korrigiert.

  • Konvertiere PNG-Kacheln in weboptimierte JPEG-Kacheln:
    node convert.js tiles/ tiles_jpeg/

Fertige Kacheln für alle \o/

Wir haben mal einige Karten-Tiles bis Zoomstufe 18 vorbereitet.
Bitte auf die jeweiligen Nutzungsbedingungen achten! Wir haben deswegen jeweils noch mal die Quelle verlinkt!
